Patent CA-2212556-C (CA)
Inventor: RUTLEDGE CHRISTOPHER L
IPC: H04B10/118
Filed: 1997-08-07
Granted: 2001-05-01
Abstract: The cells of a wireless communications system can be subdivided into smaller subcells, in each of which the available radio frequencies can be re-used to allow denser use of the system. To avoid having to run hard-wired communications links to broadcast antennas of the subcells, substantially unguided, free-space, optical communication is used between the antenna that formerly served the cell and the subcell antennas. The existing hard-wired connection from the central antenna to the remainder of the wireless communications system infrastructure continues to be used for communication to and from the cell.

Title: Fixed or adaptive deinterleaved transform coding for image coding and intra coding of video
Inventor: WUS JOHN
IPC: H04N19/593
Filed: 1997-09-03
Granted: 2002-08-20
Abstract: A coding strategy efficiently codes intra (macroblocks, regions, pictures, VOP) data. This strategy uses two basis approaches, a Fixed Deinterleaved Transform Coding approach, and an Adaptive Deinterleaved Transform Coding approach. Furthermore, within each approach, two types of coders are developed. One coder operates on an entire picture or VOPs and the other coder operates on small local regions. Using coders and decoders of the present invention, efficient coding at a range of complexities becomes possible, allowing suitable tradeoffs for a variety of applications.

Patent CA-2221936-C (CA)

Abstract: A method for the manufacture of tape tab stock that may be used to produce tape tabs for use with disposable absorbent articles, as well as a method for the on-line manufacture of tape tabs that may be manufactured concurrently with the chassis of the absorbent article to which the tape tabs will be attached. The first step is to provide a backing substrate upon which the adhesives of the tape tab can be applied. Once the backing is provided, a pressure-sensitive adhesive is applied to regions of one side of the backing substrate. (The pressure-sensitive adhesive preferably functions as the adhesive used to fasten an element of the absorbent article, such as a front waist region, to another element of the absorbent article, such as a rear waist region). The backing substrate is then slit in a direction parallel to the machine direction and the release surface of a release substrate is placed in contact with the pressure-sensitive adhesive, forming a laminate comprising the backing substrate and the release substrate. The release substrate preferably covers the entire surface of the backing substrate upon which pressure-sensitive adhesive has been applied. However, in a preferred embodiment, at least a portion of the backing substrate extends outwardly in a direction parallel to the cross machine direction beyond the longitudinal edges of the release substrate. The surface of the laminate, including the surface of the release substrate that is not in contact with the pressure-sensitive adhesive, and any of the backing substrate not covered by the release substrate is then coated with a construction adhesive. (The construction adhesive is used to join the tape tabs to the absorbent article). After the construction adhesive is applied to the surface of the laminate, the laminate is slit in a direction parallel to the machine direction and either rewound for shipping or storage, or fed to a taper unit that is integrated into the absorbent article manufacturing line. The taper unit cuts individual tape tabs and applies them to the absorbent article chassis.

Title: Pen-type injector drive mechanism
Inventor: KOVELMAN PAUL H
IPC: A61M5/172
Filed: 1996-09-06
Granted: 2008-01-22
Abstract: A medication injection mechanism, for delivering a dosage of medication from a medication cartridge having a piston, includes a two-piece drive shaft, a ratchet mechanism, and a drive mechanism. The two- piece drive shaft includes a plunger portion and a drive portion. The plunger portion has an end that contacts the piston of the medication cartridge, ratchet teeth disposed on the sides of the plunger portion that define a thickness of the plunger portion, and an openi ng to provide a passage through the plunger portion of the two-piece drive shaft. The drive portion is formed by rails that are coupled together by a connector that passes through the opening in the plunger portion so that the drive portion is coupled to the plunger portion, and can move relative to the plunger portion. Each of the rails forming the drive portion has threads on a surface that extend beyond the defined thickness of the plunger portion. The ratchet mechanism engages with the ratchet teeth of the plunger portion to permit the movement of the plunger portion toward the piston of the medication cartridge and to inhibit movement of the plunger portion away from the pisto n of the medication cartridge. Also, the drive mechanism engages with the threads on the rails of the drive portion, but is free of contact withthe ratchet teeth on the plunger portion to adjust the position of the drive portion relative to the plunger portion so that the drive portion can be moved toward the piston of the medication cartridge a fixed distance and the plunger portion is moved a distance that is less than or equal to the fixed distance.

Abstract: An apparatus and method for retrieving densely stored data from various types of magnetic media. A medium is scanned to provide an input signal. The input signal is conditioned through differentiation, equalization and partial integration. Positive and negative signal peak detectors are connected to the conditioned signal, and a threshold signal is generating corresponding to an average or midpoint of the measured positive and negative signal peaks. An output signal is generated by comparing the conditioned signal and the threshold signal. The DC component of the input signal is accounted for by feeding back the output signal and adjusting the threshold signal based on the duty cycle of the output signal.

Abstract: Methods and devices for measuring signal strengths by mobile stations in a wireless communication system are described. More particularly, while transmitting and receiving on a channel, signal strength measurements may be required. For instance, the received signal strength of broadcast information slots at the beginning of a superframe may be measured at predetermined times for several carriers. However, the mobile station may be busy performing information reception or transmission tasks. According to one exemplary embodiment, the signal strength measurements may be delayed when the mobile is transmitting and receiving on a channel, and then more frequent signal strength measurements may be made when there is no communication. In other words, the signal strength measurements do not have to occur uniformly in time, but may be more frequently performed if they have been delayed. Alternatively, the mobile station can "steal" one or more time slots to perform the signal strength measurements by ignoring its tasks of receiving and/or transmitting information.

Abstract: A pair of suspenders comprises two comparatively long straps of a given width. Each of the comparatively long straps has a front portion terminating at a front end and a back portion terminating at a back end. The back portions cross each other. Moreover, a comparatively short strap having two opposite ends is affixed at each of the opposite ends to the back portion of each of the comparatively long straps so as to define a loop, which has an overall length that is at least several times greater than the given width of the comparatively long straps. One of the straps defining each of the loops passes through the other loop, whereby the loops enable the pair of suspenders, over a range of shoulder-to-shoulder spacings, to conform automatically to the shoulder-to-shoulder spacing of a wearer. The comparatively long straps are substantially inelastic. Furthermore, an elastic strap is attached to the each of the front and back portions of each of the comparatively long straps and each of the elastic straps has a distal end, to which a fastener is attached for fastening the elastic strap to a pair of pants. Preferably, the fastener is a wire loop, which is shaped to coact with a button on the pair of pants. Alternatively, the fastener is a clip, which is adapted to clip onto the pair of pants.
